Waterways update: work in progress (1759)

Here is some information about the work of Messrs Ockenden and Omer on Irish waterways up to 1759. It is extracted from a book by Henry Brooke; Ockenden had, twenty years earlier, subscribed to support Brooke’s play. It is not impossible that they were acquainted, in Ireland or in England. Apart from anything else, both were supporters of Frederick, Prince of Wales: see A N Newman “The Political Patronage of Frederick Lewis, Prince of Wales” in The Historical Journal Vol 1 No 1 1958 on Ockenden’s post in the prince’s household at £100 a year and here on Frederick’s “many attentions” to Brooke.

Brooke’s account contains some information about Ockenden’s work that I have not seen elsewhere. I found the reference to Brooke in Thomas McIlvenna This Wonder-Working Canal: a history of the Tyrone Navigation Coalisland Canal Branch IWAI 2005.

Who was William Ockenden?

William Ockenden has been described as a Dutch engineer who worked on three eighteenth century Irish navigations: the Mallow to Lombardstown canal, the Kilkenny/Nore navigation and the Limerick Navigation [Park Canal section], all of them notably unsuccessful.

It seems likely that he was English, not Dutch, but may have lived in Ireland before inheriting property in England. But was he an engineer or a mill-owner and MP? Were there one or two William Ockendens at the time?

Here is some information and some speculation. I would welcome more of the first.

Annacotty

I have been told that the Mulkear River rose very rapidly on Saturday night and that, at one time, it was feared that the (older) bridge would be swept away. I gather that folk working in other areas were called to Annacotty to deal with the emergency.

The Mill Bar in Annacotty was closed today after being flooded.

This, from a small garden beside the bridge, suggests that the Mulkear may have carried and deposited a lot of silt

The Park Canal

I gather that the Mulkear’s waters, added to those of the Shannon itself, raised the level of the Park Canal (the bottom section of the Limerick Navigation). A problem with opening the lock gates, to release the water, meant that a few houses in Corbally were flooded. A Sinn Féin councillor, whose party colleague has been responsible [with her southern counterpart] for slashing Waterways Ireland’s budget in recent years, is quoted as saying

I am in no doubt it was primarily caused by the ineptitude of Waterways Ireland.

Alas, the news story does not tell us the source of the councillor’s certainty.

The article also says that

[…] the force of this water meant it was not possible to open the lock gates by hand.

That is, I think, misleading: neither set of gates has gate beams, so they are not opened by hand.

I see no sign of the paddles or sluices. Perhaps the level is so high that they’re underwater. I must try to check next time I’m at the canal harbour.

The upper gates in the floods of 2009

In the floods of 2009 the upper gates were held slightly open and all four sluices were discharging water. That would have lowered the level in the canal; it would also, I think, have made it easier to open the gates fully.

I am guessing, but I imagine that on Saturday night some sort of hydraulic machine was brought in this way …

Two bollards have been moved from the gateway and stacked beside it

… and used to push or pull open the near-side upper gate. There seems to be some slight damage to the stone and iron work.

Slight damage

One other possibility that struck me is that silt from the Mulkear might have built up behind the gates, making them difficult to open, but I have no evidence on the matter.

What’s a cumec, Daddy?

I don’t know, but here’s a picture of 415 of them flowing through Castleconnell. [Update 13 December: that may be only 405 cumec.]

415 cumecs on 12 December 2015

Actually, a cumec is one cubic metre of water per second, which is roughly one ton per second, which is a lot of water. And 415 cumec is the amount that, according to the blatts, the ESB is currently letting down the original course of the Shannon from Parteen Villa Weir; the minimum flow in that channel, as seen in summer, is 10 cumec.

After the summer

I don’t really know much about politicians, local or national, but I presume that, in the summer recess, they retire to their country estates for a bit of huntin, shootin and fishin, with breaks for trips to agreeable parts of foreignlandia (Tuscany, perhaps) and with occasional visits from other gentlefolk.

At any rate, something distracts them and keeps them quiet, but summer is now giving way to autumn and, er, innovative suggestions are coming thick and fast from politicos anxious to get other people to contribute to social and economic development in their constituencies (or to get reelected, whichever comes first).

So we have one who wants a walkway across Meelick Weir and another who wants a riverbus service on the Park Canal in Limerick.

Meelick turns up in another story from the past week, by John Mulligan in the Irish Independent. But despite the silly headline and subhead, the body of the article is a thorough and balanced account of flooding on the Shannon. Mr Mulligan is to be commended.

 

 

Not Grand

Limerick’s SmarterTravel initiative aims to promote cycling, walking, car sharing and public transport. It has a little leaflet (I can’t find a downloadable version) describing five walking and cycling routes and including information on bus routes, a cycle to work scheme and car sharing.

One of the cycling and walking routes is along the towing path of the Limerick Navigation from Limerick to Plassey. It is described thus:

The Tow Path was part of the Grand Canal system stretching to Dublin and was used by the Guinness brewery to bring stout to Limerick.

The towing-path was not part of “the Grand Canal system”, although I suppose it might be described as a facility used by the Grand Canal Company. The Park Canal in Limerick, and the towing-path on the river navigation to Plassey, were not built or owned by the Grand Canal Company; they were part of the independent Limerick Navigation until subsumed into the Shannon Navigation in the 1840s. The Grand Canal Company was permitted to use its vessels on the navigation when it began carrying cargoes, which it did for, amongst others, Guinness; Guinness itself did not own or operate boats on the Shannon Navigation or the Limerick Navigation.

 

The Park Canal

I wrote here about the Park Canal and why it should not be restored. I did not include, because I had not then seen it, a link to this report in the Limerick Post. It shows why the gates on the second lock were not replaced. The core problem is that the banks in the upper section of the canal slope too steeply to be stable.

The slope of the banks above the railway bridge (from a boat)

Happily, this deficiency in the original construction has saved us from another foolish restoration.

 

Canal harbour, Limerick

Went out without the camera today, alas, and found Waterways Ireland crews at work at the canal harbour in Limerick. One crew had launched a Pioner Multi (I didn’t see them do it, alas, but it may have come on the back of a truck with a HIAB or suchlike) and were hauling rubbish out of the water. Another were welding new railings to prevent access to the old hotel/canal manager’s house and installing a steel plate in a window aperture on one of the Shannon Navigation buildings.

I presume the new plate will soon be decorated. I rather like the artwork, I must say, and I think it a pity that Young Folk should not have somewhere to go to do the things that Young Folk like to do.

Annoying the neighbours

It would be unfair to condemn the proposed opening of a canal to Clones without also condemning the proposed reopening of the Park Canal in Limerick (and the Newry, when I get around to it). The link is to a top-level page; the first substantive page has a lead to the second, the second to the third and so on up to the fifth.

It’s not the bleeding Grand Canal

To Limerick City Council offices this evening, where the family of Cecil Mercier, Mill Manager of Bannatyne’s in Limerick and later supervisor of all Ranks mills in Ireland, were handing over his papers to the Limerick City Council Archive.

No photos of the Ranks boats that worked on the Shannon, alas, but perhaps there are some in the archives.

A booklet, Cecil Mercier & the Limerick Rank Mills, was distributed (free): an interesting account of the man and the industry. But it contains this sentence:

At the turn of the twentieth century there were other flour and animal feed mills in and around the city such as the Lock Mills at the junction of the Abbey River and the Grand Canal and the maize mills in Mount Kenneth and Mallow Street.

The canal in Limerick is one of five sections of the Limerick Navigation, and has recently been dubbed the Park Canal. It was not constructed by the Grand Canal Company. It was not owned by the Grand Canal Company. It was not operated by the Grand Canal Company. The only connection between that canal and the Grand Canal is that the Grand Canal Company was permitted to operate its boats on the route and was provided with premises at the canal harbour in Limerick. It put its name on the transhipment canopy, and perhaps that may have given people the mistaken idea that the Grand Canal Company owned the canal. But during the period when the GCC operated its boats, the canal was owned and operated by the Board of Works (Shannon Navigation).
